Add the minced garlic to the skillet with the onions and cook for another minute until fragrant. Stir continuously to prevent the garlic from burning, which can turn bitter.
Add the sliced zucchini to the skillet, along with the dried thyme, salt, and black pepper. Cook for about 5-7 minutes, stirring occasionally, until the zucchini begins to soften slightly and release some moisture.
In a separate bowl, combine the heavy cream and half of the shredded Gruyere cheese. Stir until the cheese is partially melted and the mixture is smooth.
Transfer the zucchini and onion mixture into an oven-safe baking dish or casserole dish. Pour the cream and cheese mixture evenly over the zucchini.
Sprinkle the remaining Gruyere cheese evenly over the top of the dish. Then, sprinkle the breadcrumbs over the cheese layer.
Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbly and the cheese is melted and gooey. Use oven mitts to handle hot dishes.
Remove the gratin from the oven and let it rest for 5-10 minutes before serving. This allows the gratin to set slightly and makes it easier to serve.
